Steve Ballmer Goes Ape During Fergie Performance at Clippers Game

Billionaire Steve Ballmer was seen hamming it up during a surprise concert by singer Fergie at Wednesday night's Clippers-Lakers game.

Footage of his dance moves instantly went viral on several social media channels, with many creating looping videos with Vine. (Note: Be sure to press the speaker button on the video below to hear Ballmer's enthusiastic yelps.)

A few fans rooting from the stands also spotted the new Clippers owner going bananas, and whipped out their phones to capture the magic. Below, viewers can also see the fancy footwork the former Microsoft CEO had in store for the Staples Center.

Apparently the whole thing was a surprise Mr. Ballmer was in on, as Fergie was sitting right next to him, courtside, when she grabbed a microphone, strutted out to center court, and rocked the audience with her latest single, "L.A. LOVE."

Deadspin noted that Ballmer wasn't the only one thrilled with Fergie's performance, pointing out a young man it dubbed "body-rollin' mop boy" who gets a little attention from Ferg as well.

The Huffington Post pointed out that Ballmer has a history of high-energy outbursts, as demonstrated by the YouTube video below showing off an old Microsoft presentation he takes by storm.
